Re: perl6 match variable

The argument-less lambda block

{ ... }

is shorthand for

-> $_ { ... }

and $/ gets passed as argument to that.

You could use

-> $match { ... }

instead to access $/ as $match

The match object $/ in not visible on its own because subst evaluates the regex in a different scope.
